Title: Double drum vacuum filter - having distribution disc in drum heads to optimise filtrate offtake
Inventor: OTTE WILHELM
IPC: B01D33/00
Filed: 1976-10-16
Abstract: Double drum filter esp. vacuum filter consists of two drums rotating in the opposite sense to each other and contacting each other. Side walls are pressed against the underside of both drums. Each drum has a control head contg. control discs with adjustable zone definition e.g. for suction and drying zones. A blowing zone is also connected into the control head, to aerate the cells. A recycle is provided of filtrate from the suction zone back into the trough, the latter being formed from the side walls and the drums. Used to filter slurries, etc. Filter allows the initial filtrate which may be loaded with solids to be recycled. In this way the clarity of the final filtrate is improved and the filter can cope with finer particles.

Title: Measuring device for gap between rolling mill rollers - uses change in inductance in transducer to measure change in gap
Inventor: MEYER ULRICH
IPC: B21B38/10
Filed: 1977-06-29
Abstract: The gap between the rollers (10, 11) of a steel strip rolling mill is measured by a device with two arms (1, 2) pivoted on a common cross beam (3). The cross beam (3) is attached to a guide (4) which slides in a hole in the frame of the rolling mill (5). The ends of the arms (1, 2) have half shells (8, 9) which match the diameters of the rollers (10, 11). The arms (1, 2) are pressed together by a tension spring (15) but can be swung open by a power cylinder (16). The two halves (12, 13) of an inductive transducer are fitted, one half to each of the arms (1, 2). Any change in the gap between the rollers (6, 7) alters the distance between the halves (12, 13) of the transducer and changes its inductance. This change in inductance is used to produce an electrical indication of the change in gap dimension.

Title: Random coder for analog and digital signals - uses synchroniser to convert irregularly arriving paris of samples into regular sequence
Inventor: MASSEN ROBERT DR ING
IPC: H03M1/04
Filed: 1978-05-10
Abstract: The random coder uses a clock generator to obtain pairs of samples between the noise source. The time spacings between pairs is constant and differs from the time spacing between the samples comprising each pair. The time spacings are chosen so that they coincide with the zero points of the autocorrelation function describing the noise source. The pairs of samples are passed to a synchroniser that converts the pairs arriving at irregular intervals into a regular sequence of equidistant samples. The clock generator selects groups of samples for conversion into a regular sequence by the synchroniser. These samples are obtained before quantisation. The synchronised samples are used to code different input signals with the aid of the noise source.

Patent DE-2834387-A1 (DE)
Inventor: NADIM AZZAM DIPL ING
IPC: G09G3/04
Filed: 1978-08-05
Abstract: An electro-optical time-indicating system displays the time by simulating a clock using dial hands. The electrodes of a liquid crystal display are formed by radial track segments and the backing electrodes are subdivided into inner and outer electrodes. The driving of the track segments to indicate hours, minutes and seconds is accomplished by a time division multiplex technique. In order to keep the number of electrode terminals for the track segments to a minimum, the track segments are combined into L track segment cascades with L input terminals. The track segments are arranged in K twin sets such that, as viewed in the clockwise direction, an nth track segment (where n ranges from 1 to L) of one set of the twin sets is always connected with the L+1-nth track segment of the other set of a twin set. The inner backing electrodes are subdivided into M inner blocks with one terminal each, and the outer backing electrodes are divided into N outer blocks with one terminal each. Each twin set is covered by two adjacent inner blocks and two adjacent outer blocks. The time-functional drive of the terminals of the track segment cascades takes place alternatingly in ascending and in descending order, and successive terminals of the inner and outer blocks are energized in a clockwise direction after every change-over between ascending and descending drive.
